Specification of Letters Patent.

Patented Feb. 211, 1922.

Application filed April 19, 1920, Serial No. 375,118.

To all whom it may concern Be it known that I, THOMAS a citizen of theUnited W. THAXTON, States, residing at in the county of Vermilion andState of Indiana, have invented certain new and use'tul lmprovements inValves; and I I do hereby declare the following to be a full,

clear, and exactdescription of the invention,

. such as will enable others skilled in the art to which it appertainsto make and use the same.

' The present invention relates to valves and the object is theprovision of a novel and improved valve for admitting air from an aircompressor or pump to a storage tank, and preventing the reverse flow,and which will be sensitive in its operation.

l/Vith the foregoing and other objects in view, which will be apparentas the description proceeds, the invention resides in the constructionand arrangement of parts hereinafter described and claimed, it beingunderstood that changes can be made within the scope of what is claimedwithout departing from the spirit of the invention.

The invention is illustrated in the accompanying drawin wherein thefigure is a perspective view showing the valve, portions being shown insection. V

In the arrangement shown, the valve device is used on a pipe 4 leadinfrom an air compressor tank 5, from which the discharge pipe 7 leads.

A valve 9 is provided for closing the end of the pipe 4 within the tank5, said valve being rounded at one end to seat against the end of thepipe, and the valve tapering to a point at the opposite end. The valveis carried by a cross head 10, the end portions of which are slidable onguide rods 11 at opposurronnd said rods and are (not shown) into an airstorage site sides of the valve 9 and pipe 4. Said rods llare secured toa bracket 12 mounted on the pipe, and coiled expansion springs 13confined between the cross head and nuts 14 screw threaded on the freeterminals of said rods. Said springs seat the valve 9 by slidingthe'cross head 10 toward the pipe, and due to the shape of the valve, itwill unseat easily for admitting compressed air from the pipe 4Ldelivered from the air compressor into the tank, the springs 13 causingthe valve to seat instantly when the flow of compressed air into thetank is stopped, so as to avoid the reverse flow 01 air from the tankinto the pipe a and air compressor. This provides a sensitive checkvalve for the end of the pipe 4.

Having thus described the invention, what is claimed as new is A valveconstruction comprising a pipe having a valve seat at the end thereof,guide rods carried by said pipe and projecting beyond said end thereof,a cross head slidable on said rods, a valve carried by said cross headand having a rounded portion to bear. against said seat, ad iustablemembers on said rods at that side of the cross head oppoite to the pipe,and expansion springs on said rods between said members and cross headand capable of individual adjustment in tension by the adjustment ofsaid members.

In testimony whereof I have signed my name to thisspecification 111 thepresence of two subscribing witnesses.

THOMAS W. THAXTON.
